Book Description
This book comprehensively introduces stripe rust disease, its development and its integral control. Covering the biology, genetics, genome, and functional genomics of the pathogen, it also discusses host and non-host resistance, their interactions and the epidemiology of the disease. It is intended for scientists, postgraduates and undergraduate studying stripe rust, plant pathology, crop breeding, crop protection and agricultural science, but is also a valuable reference book for consultants and administrators in agricultural businesses and education.

Book Description
Here we report the discovery of precise molecular marker for HTAP resistance locus in wheat cultivar Louise. Using Louise x Penawawa mapping population, coupled with data from survey sequences of wheat genome, linkage mapping and synteny analysis, we developed expressed, cleaved amplified polymorphic sequence (CAPS) marker LPHTAP2B on the short arm of wheat chromosome 2B. It perfectly segregates with the resistant phenotype and explains 62% of phenotypic variance based on disease severity, and 58% based on infection type.

Book Description
Although stem rust has been controlled by means of resistant cultivars, leaf and stripe rust continue as problems for many growing areas of the world. Wheat Rusts: An Atlas of Resistance Genes has been prepared by specialists from one of the leading international laboratories, and illustrates with colour photographs typical resistance phenotypes associated with most known genes for resistance to the three rust diseases of wheat. Relevant details for each gene include chromosome location, aspects of genetics and pathogen variation, the effects of environment on expression, origin, availability in genetic and breeding stocks, and use in agriculture. This atlas includes an introduction to host:pathogen genetics, methodologies for wheat rust research and breeding for resistance.

Book Description
Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving increased attention in the USA since the appearance of more virulent races detected in the past decade. These races caused yield losses even in areas where the disease previously was rarely detected. Host plant resistance is the most cost effective and environmentally friendly means of controlling stripe rust. Deployment of single, major genes for resistance has been compromised due to the genetic variability of the pathogen, emphasizing the need to breed for durable resistance. 'Stephens' wheat (Triticum aestivum L.) has been grown commercially in the Pacific Northwest region of the USA for 30 years and shows resistance to P. striiformis f. sp. tritici "old" and "new" races. The durable resistance of Stephens to stripe rust is believed to be due to a combination of seedling and adult plant resistance genes. Multilocation field trials and molecular genotyping were used to study the genetics of the resistance response in 'Stephens'. Disease severity, based on the percentage of leaf area infected in field plots, was recorded in eight locations: five in 2008 and three in 2009. Locations could be divided into two mega-environments based on time of appearance of disease and QTL identified. Quantitative trait loci (QTL) analysis identified 11 chromosomal regions associated with resistance to stripe rust in the resistant parent ('Stephens') and two regions derived from the susceptible parent ('Platte'). Many QTL locations coincided to those of previous reports. Furthermore, this study suggests that a combination of additive resistance genes acting at different plant stages is responsible for the durable resistance of 'Stephens'. Significant QTL x environment interactions were found, suggesting that specificity to plant stage, race, and/or temperature are responsible for different disease responses.
